摘要：
The influence of grain size on the tensile deformation and ductility for Mg-1.02% Zn (wt.%) alloy was investigated. The uniform elongation is nearly insensitive to the increase of grain size, but the post-uniform elongation is significantly decreased with increasing grain size. The high ductility in the fine-grained samples is due to the lower frequency of twins and increased dynamic recovery from the enhanced activation of prismatic < a > slip.
